COVID-19疫情导致人们的预算、时间的机会成本以及购买和消费食物的地点发生重大变化。我们使用有关从商店、外卖店、餐馆和其他商店购买食品和非酒精饮料的新数据，估计疫情对一个大型、有代表性的英国家庭饮食的影响。我们发现，在家里消耗的卡路里的大量和持续的增加超过了在外面吃的卡路里的减少。与疫情前相比，2020年3月至7月，家庭的总热量增加了280卡路里/成人/天，7月至2020年底增加了150卡路里/成人/天。尽管数量增加，但在大流行期间饮食质量几乎没有变化。所有社会经济群体的卡路里摄入量都有所增加，社会经济地位最高的家庭增加最多，退休家庭增加最少。我们估计，在大流行爆发两年后，这些变化可能会使超重的成年人比例增加至少5个百分点。
The COVID-19 pandemic led to significant changes in people’s budgets, the opportunity cost of their time, and where they can purchase and consume food. We use novel data on food and non-alcoholic drink purchases from stores, takeaways, restaurants and other outlets to estimate the impact of the pandemic on the diets of a large, representative panel of British households. We find that a substantial and persistent increase in calories consumed at home more than offset reductions in calories eaten out. Households increased total calories relative to pre-pandemic by 280 per adult per day from March to July 2020, and by 150 from July to the end of 2020. Although quantity increased, there was little change in diet quality over the pandemic. All socioeconomic groups increased their calorie intake, with the largest rises for the highest SES households and the smallest for retired ones. We estimate that the changes could increase the proportion of adults who are overweight by at least five percentage points, two years after the pandemic onset.
